The Reverse Water-Gas Shift Reaction as an Intermediate Step for Synthetic Jet Fuel Production: A Reactor Sizing Study at Two Different Scales

In the context of the energy transition and the growing imperative to develop decarbonised solutions for the transportation sector, our team is investigating the conversion of CO2 to kerosene via a Power-to-kerosene process. Given the high stability of the CO2 molecule, an activation step is essential to convert it into more complex molecules. The reverse water-gas shift (rWGS) reaction is a promising solution to achieve this conversion. A primary objective of this project is to design and construct a small pilot facility that synthesises kerosene from CO2 and H2, calibrated to an available electrolysis capacity of 1.5 Nm³/h. This study focuses on the sizing of the rWGS section for this scale and further compares it to a larger system with an electrolysis capacity 1,000 times greater.
